[QUOTE="ohiobass, post: 213841, member: 3941"] Picked up a 1973 Evinrude Fisherman 6hp for my 1982 Sears gamefisher aluminum semi V boat. Motor has an aluminum 8x7 prop, 8 pitch -7" diameter (factory prop) had it out yesterday for the first time, and got around 7-1/2 mph gps top speed, with me (210 lbs) 29 series battery (around 80 lbs) gas tank (around 20 lbs) and tm on front (around 30 lbs) Only way I got to 7-1/2 mph is to place battery at center of boat. If placed back by transom, there was too much weight at back, and it wouldn't get out of it's own way!!! Thought I'd get closer to 10mph.??? What do ya think? maybe a different prop pitch???? (which they really don't have much selection in the 6hp) Was thinking going with a 3 blade, but only ones out ther for it are the same pitch/diameter, and that would only make it more sluggish in hole shot and top end. 8) Thanks in advance, jeff 8) **************UPDATED WITH MORE INFO, IN POST BELOW************ 8) 8) [/QUOTE]
